HUB AND SPOKE CONNECTION.

To all 10/ 10722 it may concern:

Be it known that 1, Planner 0. Cox, a citizen of the United States residing at Annapolis, in the county of Anne Arundel and State oi" ;rlaryland. have invented certain new and useful lm iirovcments in Hub and Spoke Connections; and I do hereby declare the following to be a t'ull clear and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same This invention relates to vehicle wheels and more particularly to a wheel oi the type including spring spokes which operate to neutralize and absorb shock and vibration whereby it is possible to utilize a solid tire and thereby obviate the annoyance incident to pneumatic tires generally provided for automobiles and motor vehicles.

The invention consists of a wheel embodying a rim, a hub and spring spokes, the latter having portions reversely curved to admit ot' the wheel yielding so as to compensate for shock and vibration.

tlther objects and advantzures will be apparent and suggest themselves as the nature of the invention understood.

ir'hile the drawings illustrate an emhodi ment of the invention it is to be understood that in adapting the same to meet different conditions and requirements, various changes in the term, proportion and minor details of construction may be resorted to without departing from the nature of the invention.

Referring to the accompanying drawings forn'iing a part of the ap 'ilication,

Figure l is a side view 'ot a partof a spring wheel embodying the invention.

Figure 2 is a sectional detail view in an axial plane (it the wheel showing the hub and one spoke and Figure 3 i a side elevation of the inner hub portion.

Corresponding and like parts are referred to in the following description and designated in the several views of the drawings by like reference characters.

The Wheel embodies a rim 1 which may be of any construction depending upon the SeriaI No. 553,746.

nature (it the tire to be titted thereto. or lugs 2 project inwardly from the rim 1 at regular inter 'als and may be provided in any manner, either as a part of the rim or secured thereto in any preferred way as by being welded or brazed thereto.

The hub comprises a box 3 and a shell l screwed or otherwise fastened to the box and having outer extensions 5 to receive the inner ends of the spokes which. are fastened thereto in any manner. The nor; 3 may be cast and the shell 4r of sheet metal such as steel.

The spring spokes (5 have portions reversely curved and are attached at their outer ends to the lugs 2 of the rim and at their inner ends to the extensions 5 ot the hub. The spokes may be attached to the respective parts in any preferred way to admit of their ready replacement should occasion require.

The shell t comprises mating sections at and l The section t has an annular plate or ring 7 and section. i" a corresponding plate or ring 7. 8 is an externally and internally threaded annular boss extending at one side of the plate or ring 7 and 9 a lateral annular flange extending from the other side thereof. Ring 7 has an internally threaded boss S extending therefrom and a lateral annular flange 9 extending troin its other side, said flange 9 being of a reduced diameter to lit snugly within flange 9. 10 are rivets to hold the flanges S) and 9 together when the hub assembled as shown in Figure 2. A cup-shaped nut 11 is provided to lit the external threads of boss 8.

hat is claimed is:

A wheel hub having a plurality of lllll) sections each section being in a single piece and having an outwardly extending boss, the interior diameter of one of the bosses being greater than that of the other boss, each section having an annular inwardly extending flange arranged outwardly of its boss, said flanges being in telescopic rela tion, means at and securing said flanges together against lateral separation and circumierential movement, a box spanning said Ears plates and surrounded by said flanges, said to facilitate attachment of spokes to and box extending into said bosses and being between the sections. 10 screw threaded to each of them to afford n testimony whereof I aflix my signaa connection between the box and each sechire in pr enc of tWO Witnesses.
